Monument in Mexico pays tribute to those lost to drug violence

A man visits the "Memorial to Victims of Violence in Mexico" during its opening in Mexico City on April 5. The massive 149,000-square foot monument serves as a tribute to the victims of Mexico's bloody drug war. The first of its kind in Mexico, it is divided into several iron panels featuring poems and quotes. An estimated 70,000 people have been killed by drug-related violence in Mexico in the past seven years, and many thousands of others remain unaccounted for.
